The word "引吭高歌" is formed by combining two verbal phrases: "引吭", meaning to stretch the throat (引 drawing or pulling, 吭 throat), and "高歌", meaning to sing loudly (高 high, 歌 sing). The sequence depicts the physical action of preparing the vocal cords followed by the act of singing at a high volume, resulting in a literal meaning of "draw the throat and sing high" to convey enthusiastic singing.
